Layer Separation/Delamination
Medium to Fix
Printed layers don't stick together properly, causing the print to split apart along layer lines.
What Does It Look Like?
Layers visibly separated or cracked
Print splits apart easily along layers
Gaps visible between layer lines
Common Causes
Print temperature too low
Insufficient cooling between layers
Layer height too large
Dirty nozzle
Solutions (Try in Order)
Start with Priority 1 solutions. Make one change at a time and test between changes.
1
Increase Print Temperature
Higher temp improves layer bonding
Increase by 5-10°C (stay within filament range)
1
Reduce Cooling Fan Speed
Less cooling allows better layer fusion
Reduce fan to 50% or lower (especially for first 5-10 layers)
2
Decrease Layer Height
Thinner layers bond better
Try 0.2mm or 0.16mm instead of 0.28mm
2
Increase Extrusion Multiplier
More material creates better contact
Increase flow rate by 2-5%
3
Clean or Replace Nozzle
Clogs reduce material flow
Cold pull or nozzle replacement
Prevention Tips
- Save working settings for each filament type
- Perform regular printer maintenance
- Keep filament dry and stored properly
- Re-level bed before important prints
- Start with manufacturer-recommended settings
